Output of measured values
In addition to navigation and landmark detection, the NAV350 can output the measured
surrounding contour to the host connected (mixed mode).
The measured values can be transmitted to a computer system connected and evaluated
here (see
section 3.9.2 “Data communication using telegrams” on page 32
). The host can
calculate the position of the AGV from these measured values.
Navigation based on the surrounding contour measured is useful in places in which it is not
possible to attach any reflectors, for example in truck cargo bays.
Fig. 17:
Output of measured values for truck loading
The NAV350 outputs the following measured values at its data interfaces:
•
profile of the field of view in two-dimensional polar coordinates
•
contents of one revolution (360°): among other data, starting angle for the scan, step
width, time stamp for start of the scan, number of measured values, value and direction
of the measured distance, remission value of the object measured
Important
It is only possible to output all measured values of a 360° scan in real-time using the Ether-
net interface.

Integration of the NAV350 in an AGV’s control system
Recommendation
The integration of an NAV350 in an AGV’s control system requires sound programming skills
in the area of vehicle control. In addition knowledge of the data exchange between a laser
positioning sensor such as the NAV350 and the vehicle computer are required. We there-
fore strongly recommend you make use of the training offered by SICK AG on the Hamburg
site.
3.9.1
Data interfaces
The NAV350 has a serial host interface and an Ethernet interface. The NAV350 is config-
ured with the aid of SOPAS ET via these interfaces. The NAV350 also communicates with
the AGV’s vehicle computer via its interfaces.
